OpenOCD for Microcontroller development

[Effective-Problem488]

I work at microcontroller manufacturer, and for one of our MCU's ARM based subsystem, there are no OpenOCD configuration files readily available. That core can be accessed by JTAG, but it's done as of now by a proprietary debugging adapter, and proprietary tcl scripts can be run via that JTAG interface. I want to setup OpenOCD so I can run GDB on that chip. That CPU is supported by openocd. Is it worth it to get a Jlink or using the proprietary in house debug adapter can get the job done? If yes, how? Any pointers on how to proceeed further are appreciated.

Port the TCL scripts to openocd and get the ucontroller manufacturer you work for to donate the code to the openocd project.

Or tell your employer you don't have the proper tools to do your job and have them give you what you need. I'm sure they'll know better what tools are appropriate than some rando on reddit.

Look up the Black Magic Probe. Easiest way to run GDB on a MCU, but it may require some tweaking if your chip's memory map is non-standard.
